Abstract

A device and method for improving hydration of a biomaterial includes a syringe having a cavity therein and a distal opening, an end cap, and a wall operatively coupled to the end cap. The end cap has a distal plate with an inlet and is removably attached to the syringe to cover the distal opening. The wall is positioned proximate to the inlet and at least partially defines a volume in fluid communication with the inlet. An orifice extends through the wall and fluidly connects the volume to the cavity. A flow of a liquid component of biomaterial diffuses through the orifice and is introduced into a particulate component of biomaterial. As such, the liquid component of biomaterial hydrates the particulate component of biomaterial.

First claim

What is claimed is:

1. A device for improving hydration of a particulate component of biomaterial with a liquid component of biomaterial, the device comprising:
a syringe having a syringe body and a cavity therein for containing the particulate component, the syringe body including a distal opening;
a distal plate removably connected to the syringe body and at least partially covering the distal opening, the distal plate having an inlet extending therethrough for receiving the liquid component;
a wall connected to the distal plate and positioned within the cavity, the wall at least partially defining a volume in fluid communication with the inlet, and the wall being configured to maintain the volume between the inlet and the particulate component within the cavity of the syringe; and
at least one orifice extending through the wall and fluidly connecting the volume to the cavity such that the liquid component received by the inlet flows throughout the volume and into the cavity via the at least one orifice for diffusion of the liquid component and hydration of the particulate component within the cavity of the syringe,
wherein a cross-sectional area of the at least one orifice is less than a cross-sectional area of the inlet.

2. The device of claim 1 wherein the at least one orifice includes a plurality of orifices for diffusing the liquid component and hydrating the particulate component.

3. The device of claim 2 wherein each of the plurality of orifices is generally circular in shape and the orifices are distributed generally evenly throughout the wall.

4. The device of claim 1 wherein at least a portion of the distal plate forms an end cap, and the end cap is removably attached to the syringe body and covering the distal opening.

5. The device of claim 1 wherein at least a portion of the wall forms a baffle plate.

6. The device of claim 1 wherein at least a portion of the wall forms a cannula.

7. The device of claim 1 wherein a portion of the wall forms a baffle plate and another portion of the wall forms at least one cannula.

8. The device of claim 1 , wherein the wall is fixed to the distal plate.

9. A diffuser for improving hydration of a particulate component of biomaterial with a liquid component of biomaterial, the particulate component contained within a cavity of a syringe, the diffuser comprising:
a distal plate configured for removable attachment to the syringe, the distal plate having an inlet extending therethrough for receiving the liquid component;
a wall connected to the distal plate and configured to be positioned within the cavity, the wall at least partially defining a volume in fluid communication with the inlet, and the wall being configured to maintain the volume between the inlet and the particulate component within the cavity of the syringe; and
at least one orifice extending through the wall and configured to be in fluid communication with the volume such that the liquid component received by the inlet is configured to flow throughout the volume and through the orifice for diffusion of the liquid component and hydration of the particulate component within the cavity of the syringe,
wherein a cross-sectional area of the at least one orifice is less than a cross-sectional area of the inlet.

10. The diffuser of claim 9 wherein the at least one orifice includes a plurality of orifices for diffusing the liquid component and hydrating the particulate component.

11. The diffuser of claim 10 wherein each of the plurality of orifices is generally circular in shape and the orifices are distributed generally evenly throughout the wall.

12. The diffuser of claim 9 wherein at least a portion of the distal plate forms an end cap, and the end cap is configured to removably attach to the syringe.

13. The diffuser of claim 9 wherein at least a portion of the wall forms a baffle plate.

14. The diffuser of claim 9 wherein at least a portion of the wall forms a cannula.

15. The diffuser of claim 9 wherein a portion of the wall forms a baffle plate and another portion of the wall forms at least one cannula.

16. The diffuser of claim 9 , wherein the wall is fixed to the distal plate.

17. A method of improving hydration of a particulate component of biomaterial with a liquid component of biomaterial, the particulate component contained within a syringe and positioned against a wall having at least one orifice extending therethrough, the wall being connected to a distal plate having an inlet, the distal plate being removably connected to the syringe, the method comprising:
diffusing a flow of the liquid component through the inlet of the distal plate and the at least one orifice in the wall in order to form at least one diffused flow of liquid component;
introducing the diffused flow of the liquid component into the particulate component within the syringe; and
distributing the liquid component throughout the particulate component in order to hydrate the particulate component with the liquid component.

18. The method of claim 17 wherein at least a portion of the wall forms a baffle plate, the method further comprising:
directing the flow through the baffle plate.

19. The method of claim 18 wherein the at least one orifice extends in a generally longitudinal direction, the method further comprising:
directing the diffused flow of the liquid component into the particulate component in the generally longitudinal direction within the syringe.

20. The method of claim 17 wherein at least a portion of the wall forms at least one cannula, the method further comprising:
directing the flow through the at least one cannula.

21. The method of claim 20 wherein the at least one orifice extends in a generally transverse direction, the method further comprising:
directing the diffused flow of the liquid component into the particulate component in the generally transverse direction.

22. The method of claim 17 wherein a portion of the wall forms a baffle plate and another portion of the wall forms at least one cannula, and diffusing the flow further comprises:
directing the liquid component through the baffle plate and through the at least one cannula.

23. The method of claim 22 wherein at least one orifice extends in a generally longitudinal direction and at least one other orifice extends in a generally transverse direction, the method further comprising:
directing at least one diffused flow of the liquid component into the particulate component in the generally longitudinal direction; and
directing at least one other diffused flow of the liquid component into the particulate component in the generally transverse direction.

24. The method of claim 17 wherein the at least one orifice includes a plurality of orifices, the method further comprising:
dividing the flow of the liquid component through the plurality of orifices to create a plurality of diffused flows of liquid component.

25. The method of claim 17 wherein the wall is operatively connected to an end cap having an inlet, the method further comprising:
fluidly coupling a source of the liquid component to the end cap; and
fluidly communicating the liquid component through the inlet and toward the wall.

26. The method of claim 17 , wherein a volume is at least partially between the wall and an inlet, the method further comprising:
introducing a first liquid material and a second liquid material into the vo
